.SH DESCRIPTION
.sp
.LP
\fBset_item_init()\fR assigns the application-defined function to be called
when the \fImenu\fR is posted and just after the current item changes.
\fBitem_init()\fR returns a pointer to the item initialization routine, if any,
called when the \fImenu\fR is posted and just after the current item changes.
.sp
.LP
\fBset_item_term()\fR assigns an application-defined function to be called when
the \fImenu\fR is unposted and just before the current item changes.
\fBitem_term()\fR returns a pointer to the termination function, if any, called
when the \fImenu\fR is unposted and just before the current item changes.
.sp
.LP
\fBset_menu_init()\fR assigns an application-defined function to be called when
the \fImenu\fR is posted and just after the top row changes on a posted menu.
\fBmenu_init()\fR returns a pointer to the menu initialization routine, if any,
called when the \fImenu\fR is posted and just after the top row changes on a
posted menu.
.sp
.LP
\fBset_menu_term()\fR assigns an application-defined function to be called when
the \fImenu\fR is unposted and just before the top row changes on a posted
menu. \fBmenu_term()\fR returns a pointer to the menu termination routine, if
any, called when the \fImenu\fR is unposted and just before the top row changes
on a posted menu.
.SH RETURN VALUES
